分别选用3种填料(滤泥、油茶壳、油茶果壳炭)进行协同活性污泥强化生物降解油烟污染物动力学实验研究,结果表明,用Lawrence-Mc Carty模型能较好地反映出油烟污染物的降解规律,确定其动力学参数一级降解速率常数分别为0.000 099、0.000 043、0.000 060、0.000 061 L/(mg·h),最大比降解速率分别为0.003 6、0.011 0、0.009 8、0.017 4 mg/(mg·h),一级降解反应的液相油烟浓度分别36.46、255.50、163.29、288.19 mg/L。
Three types of packing including filter mud,camellia oleifera shell(COS),camellia oleifera shell carbon(COSC),associated with scrubbing solution was selected for the kinetic experiment of biodegrading cooking fume pollutants.The results show that Lawrence-Mc Carty model can appropriately reflect the degradation law of cooking fume pollutants. The first order rate constants were 0.000 043,0.000 060,0.000 061 L/(mg·h) respectively,the maximum specific degradation rates were 0.011 0,0.009 8,0.017 4 mg/(mg·h),and the first order degradation reaction of liquid-phase cooking fume concentration were 255.50,163.29,288.19 mg/L respectively.
